Clackamas County plans to take out a $20 million state loan so five road construction projects won't be delayed by rising costs of land, materials and fuel.

Without the loan, some of the projects would be delayed by several years or dropped, county spokeswoman Ellen Rogalin said. The county plans to pay back the loan over 15 years with money collected from one-time fees charged to new or expanding developments in unincorporated Clackamas County.
